• LED Modules will be packaged in trays for primary protection.
• According to the total delivery amount, cardboard boxes will be used to protect the trays of LED Modules from mechanical shocks during transportation.
• The boxes are not water resistant and therefore must be kept away from water and moisture.
Reliability and Average Lumen Maintenance
Before releasing new products the manufacturer puts a representative product sample set through an entire suite of qualification tests, including the most stressful
test for high power LEDs, the Wet High-Temperature Operating Life (WHTOL) test at 85°C/85%RH for 1000 hours at the specified operating current.
LED lifetime has been extrapolated based on the accumulated operating and accelerated aging data. Based on this data, the manufacturer projects that the LED
products will deliver, on average, 70% lumen maintenance at 50,000 hours of operation at the specified operating current, provided that the case temperature is
